If you are using WordPress and did a little reading about WordPress Security, then you should have seen a mention of WordPress Security Keys (Secret Keys). In this article, we will explain the what, why, and hows of WordPress Security Keys for WordPress Beginners.

These security keys makes it harder to crack your password. A non-encrypted password like “username” or “wordpress” can be easily broken, but a random, unpredictable, encrypted password such as “88a7da62429ba6ad3cb3c76a09641fc” takes years to come up with the right combination.
